Abstract

PROBLEM TO BE SOLVED: To solve such a problem that it takes a long time because interference takes place between a cable clamp and a cable and the cable turns out to be unable to be inserted through the cable clump to make designing to be redone or the like because the conventional CAD device is not provided with a suffi cient support function in regard to the shape design of the cable that goes through the cable clamp. SOLUTION: First, the cable to be passed through the cable clamp is designated (S1). Next, an area needed to make the cable pass through from the cross-section area of each cable is calculated, and compared with the internal diameter area of the cable clamp to perform verification (S3 and S7). In the preparation of a cable shape, first, the control point position of a cable route is designated inside the cable clamp (S8). The cable shapes can collectively be prepared by adding the calculated control point position to the existing cable route control point position of each cable (S10 and S12).

DESCRIPTION OF THE PREFERRED EMBODIMENTS A cable clamp and a cable shape designing method of the present invention are applied to a three-dimensional CAD apparatus using an information processing apparatus such as a general-purpose computer, a workstation, or a personal computer. The realization means depends on a procedure for causing software, that is, hardware, to execute a specific process. Therefore, the present invention is not limited to the types of hardware constituting the three-dimensional CAD device. Therefore, the configuration of hardware using the method of the present invention is not specifically illustrated.

Each of the cables 1, 2, and 3 is a cable that has attribute data such as “cable diameter” and “minimum bending radius”, and has already been given a “cable route control point (excluding the portion to be clamped)”. . In this specification, the “minimum bending radius” may be simply referred to as “bending radius”.

The verification of the cable clamp is performed as follows. First, a cross-sectional area of each cable passing through the cable clamp is calculated, and an area necessary for accommodating three cables is obtained based on the calculation result (with a predetermined margin). Then, the area required for the storage and the inner diameter area of the cable clamp are compared. This makes it possible to verify whether the specified cable clamp can be used.

The creation of a cable shape passing through a cable clamp is performed as follows. First, as shown in FIG. 5, the position of the cable passing through the cylindrical cable clamp 10 is determined. In the example of the figure, three cables of cable 1, cable 2, and cable 3 are arranged from the upper left,
This is an example of passing through a cable clamp 10.

Next, as shown in FIG.
The control point positions of the cables are determined so that a few pass through the cable clamp 10 perpendicularly to the end face of the cable clamp. Further, a control point at a position separated by a cable bending radius on a perpendicular line from the cable clamp end face is obtained. Points indicated by black circles in FIG. 6 correspond to this. Then, by adding the obtained control point position to the existing control point position of each cable, the cable shape passing through the cable clamp is
It can be created collectively with the cable shape of other parts.

Further, by adding the newly obtained position of the cable route control point in the clamp to the data of the cable clamp, when the movement of the cable clamp is slight, only the replacement of the control point data in the cable clamp is performed. The change of the cable route is completed.
